CAR-END SHEET.

Application filed February 21, 1912.

To all whom it may concern:

Be it known that 1. WILLIAM N. Onrriu,

a citizen the United States, and resident of lliilCllll u i Lity, county of Laporte, and CU. 14 I! mate or Indiana, have invented ceitain an end for a gondola car, but obviously might be applied to an end for a box car, either by increasing its height or by using a plurality of plates one above the other.

In the accompanying drawings:

Figure 1 shows an end view of the car body;

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1.

The plate is indicated as being made of metal which is thicker at its lower portion, 1, than at its upper portion, 2, and moreover is thicker at its central portion. 3, than at its end portions, l. The thickness is graduated from the thicker to the thinner portions. The plate is shown as having end portions bent at an angle, as shown at 5, so as to lap past the sides 6 of the car body and attach thereto. To produce increased stiffness of the plate, which increased stiifness shall extend substantially to the margins thereof and shall be operative in diagonal vertical and horizontal directions, corrugations of peculiar configuration are shown. These corrugations are indicated as comprising a central transverse corrugation 7, shown as slightly narrower at each end than toward the middle and having an enlargement or extension at its mid. dle portion 8, both above and below the line of the corrugation. The variation of width between middle and end portions of corrugation T is preferential but not necessary to the carrying out of my invention.

Marginal corrugations spaced from the top and bottom margins ofthe plate are indicated at 9. These various corrugations are struck out from the common plane of Specification of Letters Patent.

Serial No. 278,436.

the plate, in which plane the top, bottom and end margins of the plate lie. The marginal corrug ns 9 preferably extend to a line nearer the end of the plate than does the central corrugation 'Z. Extending from each end of each of the marginal corrugations is a diagonal corrugation or rib 10. These diagonal corrugations intersect at the vertical median line of the plate, and each pair lies wholly either above or below the horizontal median line, of the plate.

As shown, the acute angle formed by the juncture of the diagonal corrugations with each other, and with the marginal corrugation, is raised to correspond with the corrugations, thus producing virtually a widening of the struok-out portion, as indicated at 12. This peculiar arrangement of corrugations or ribs, and the arrangement of the metal as to thickness, each'increases both the strength and stiffness of the car end and together produce an end plate of great stiffness when considered in connection with its weight.

I claim as my invention 1. A car end comprising an integral plate formed with the thickness of the material of which it is composed diminishing by uniform gradation from its center to its ends.

2. A car end comprising a plate whose greatest thickness of material is at its bottom edge and which tapers uniformly to a least thickness of material at its top and the material of which is thicker at its center transversely than at its ends.

3. A car end comprising a plate having raised portions struck out therefrom, the

raised portions spaced inwardly from the margins of the plate on all edges thereof, the raised portions comprising a transverse central rib, transverse marginal ribs parallel thereto near the upper and lower margins of the plate, and diagonal ribs extending from each end of each marginal rib to a point near the ends of the central rib.

4:. A car end comprising a plate having its top, bottom and end margins in a common plane, a transverse rib struck out from the plane of the plate and having a lateral enlargement at its middle portion, said rib being located approximately at the horizontal 'niedian line, marginal ribs parallel to and spaced from the upper and lower margins of the plate and terminating short points each on its own side of the central rib spaced from the end margins of the plate equidistantly With the ends of the marginal ribs, the material of the plate in the acute angles of intersection of said ribs being raised to form a part of said ribs whereby the ribs become wider at these points of intersection, the material of the plate and corrugations being thickest at the bottom of the plate and diminishing in thickness uniformly to its top.

5. A car end comprising a plate having top, bottom and end margins in a common plane, a central transverse rib having a vertical enlargement struck out from the common plane, marginal ribs spaced from the rpper and louver margins of the plate and terminating nearer the ends of the plate than does the central rib, diagonal ribs extending from each end of each marginal rib to the line connecting the opposite ends of the marginal ribs, pairs of diagonal. ribs intersecting upon the transverse center of the plate and each pair lying Wholly above or wholly below the central rib, the thickness of material of the plate diminishing uniformly from bottom to top and from the center horizontally to each end of the plate.

6. A car end comprising a plate having parallel corrugations arranged near its 1nargins and median line. each said corrugation extending substantially the full Width of the plate, and obliquely arranged corrugations coinciding at one end With said marginal corrugations, the arrangement about an axis 2;

oi the plate being symmetrical.
